1、常用各种数据校验方法源代码BorlandC++Builder5.0//-----------------------------------------------------------------------------//定义数据类型缩写形式typedefunsignedcharuchar;//无符号字符typedefunsignedshortushort;//无符号短整型typedefunsignedlongulong;//无符号长整型typedefunsignedintuint;//无符号整型typedefDynamicArrayTByteDynArray;//

2、动态定义字节数组//CRC8位校验ucharCRC8Valid(constuchar*puchData,intlen){ucharcrc8=0;while(len--){crc8=crc8^(*puchData++);}returncrc8;}//---------------------------------------------------------------------------//CRC8位校验ucharCRC8Valid(constTByteDynArraypuchData,intlen){ucharcrc8=0;intindex=0;while(len--){c

3、rc8=crc8^puchData[index++];}returncrc8;}//---------------------------------------------------------------------------//和校验ucharSumValid(constuchar*puchData,intlen){ucharcrc8=0;while(len--){crc8=crc8+(*puchData++);}returncrc8;}//-------------------------------------------------------------------

4、--------//和校验ucharSumValid(constTByteDynArraypuchData,intlen){ucharcrc8=0;intindex=0;while(len--){crc8=crc8+puchData[index++];}returncrc8;}//---------------------------------------------------------------------------//从第index位开始进行校验ucharSumValid(constuchar*puchData,intindex,intlen){ucharcrc8=0;

5、puchData+=index;while(len--){crc8=crc8+(*puchData++);}returncrc8;}//---------------------------------------------------------------------------//从第index位开始进行校验ucharSumValid(constTByteDynArraypuchData,intindex,intlen){ucharcrc8=0;intindexs=0;indexs+=index;while(len--){crc8=crc8+puchData[indexs++

6、];}returncrc8;}//---------------------------------------------------------------------------//CRC16校验ushortCRC16Valid(constTByteDynArraybuffer,intlen){ushortcrc=0,tmp;intindex=0;while(len--){tmp=buffer[index++];crc=crc^(tmp<<8);for(inti=0;i<8;i++){if(crc&0x8000)crc=(crc<<1)^0x1021;elsecrc<<=1;}

7、}crc=(crc>>8)

8、(crc<<8);return(crc);}//---------------------------------------------------------------------------//CRC16校验ushortCRC16Valid(constuchar*buffer,intlen){ushortcrc=0,tmp;while(len--){tmp=*buffer++;crc=crc^(tmp<<8);for(i
